On ClimateNest's 0–10 suburb hazard index, Chatsworth scores 4 for flood risk — a moderate exposure relative to the Australian suburb range. For comparison, properties in Chatsworth can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.
